How to Find Your Keurig Serial Number

Keurig organizes home-brewer serial numbers by specific locations on the machine. This guide uses the official model lists provided by Keurig to help you identify where to look.

Important Note: This guide covers home brewers only. It does not provide a public decoder to determine your exact model or warranty status from the number alone; for those needs, please refer to official support channels.

Keurig home brewer serial-number locations grouped by exact model: behind a side reservoir, behind a rear reservoir, or on the brewer bottom. — Match the exact model name to Keurig’s side, rear, or bottom location group; older K-Classic and K-Duo Plus need the separate exception checks below.

Important Exceptions and Ambiguities

The K-Classic Exception

For older K-Classic brewers, the location may differ. If you do not find a serial number behind the reservoir, remove the drip tray and look into the cutout at eye level.

For an older K-Classic, first check behind the water reservoir; if the serial number is not there, remove the drip tray and look into the cutout at eye level. — Older K-Classic: check behind the reservoir first, then use Keurig’s drip-tray cutout check if the label is not there.

The K-Duo Plus Ambiguity

The official Keurig support page lists the K-Duo Plus in both the rear-reservoir group and the bottom-location group. Check both locations rather than assuming one applies to every K-Duo Plus.
